SKYLIGHT.

SPECIFICATION forming part of Letters Patent No. 334,651, dated January 19. 1886.

Application filed November 1 2, 1885. Serial No. 182.68. (No model.)

To all whom it may concern Be it known that I, J OSEPH F. FORDERER, of the city and county of San Francisco, State of California, have invented an Improvement in Skylights; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to certain improvements in skylights; and it consists of a skylight having a ridge-ventilator connected with it, and openings or passages for the purpose of ventilation, with certain details of construction, which will be more fully described by reference to the accompanying drawing, in which the figure is a view of my skylight and ventilator.

My skylight is composed of a frame-work" having parallel hollow bars A B, formed with channels for the reception of the glass, and ventilating-passages G through the hollow bars. \Vhere these skylights are formed upon each side of a ridge, the upper ends of the skylight-bars A B are cut off, so as to leave them open, and this portion of the skylight is covered by what is termed a ridge-ventilator, having vertical sides and a roof, J. The heated air, which usually collects beneath the ventilator, rises into the space beneath the ridge-ventilator J, and in order to carry this off and equalize the temperature openings K are made in the sides near the junction with the skylight, through which the air may be admitted to its interior. Beneath the roof J of this ventilator are passages L, which extend along from its apex to the eaves, as shown, opening outward upon one side of the ridge at one end, while the other ends open just beneath the eaves at the opposite side. When the wind blows from one side, it will pass in through the openings K upon that side and create an upward draft within. At the same time the air passes through the passages L, which decrease in size toward the eaves, thus increasing the velocity of the air current,

which, being discharged near the openings at the eaves, through which the foul air escapes, creates a considerable draft, which tends to carry away the foul air as fast as it accumulates.

Having thusdescribed my invention, what A I'claim as new, and desire to secure by Letters JOSEPH FORDERER.
